It is far easier to provide an example for what I am trying to describe than to try and articulate it:
Example:
Scholar A: "Wow. That new study from University X is getting a lot of attention."
Scholar B: "I don't get what's so great about it. It doesn't seem that revolutionary to me."
Scholar A: "It's not. It's only receiving this much attention because University X is so prestigious."
Scholar B: "Ah. You mean the blank effect?"
I can't quite place my finger on it, but I know there is some pithy expression to describe this phenomenon.
Note: "Looking for idiom/expression to describe an instance where one makes something seem better than it really is" is not quite what I am referring to, as the study was not deliberately "fluffed up".
